Water’s importance in sustaining life is a no-brainer. It is infact so important that scientists search for signs of water on other planets to ascertain whether they once sustained life or could in the future. ⅔ of the earth is composed of water and surprisingly this statistic is reflected in the human body as well. Our bodies are composed of 70% of water, our brains, the seat of our personality thoughts and emotion, upto 75%.
From the moment we ingest water, it helps us in various functions such as with
- Thermogenesis (body temperature management),
- Digestion of food,
- Assimilating nutrients
- Providing oxygen to every cell, and finally
- Excretion of waste material.
During this whole process we constantly lose water by sweating, breathing and through excretion and elimination. It is essential that we rehydrate frequently to ensure smooth function of our body. Less water can put unnecessary strain on the body, slow down metabolism and in fact cause us to gain weight as the body then tries to hold on to water in attempts for self-preservation.
Some other symptoms of possible dehydration can include
- Dark urine,
- Dry lips and mouth.
- Irritable mood,
- Confusion and feeling muddled
- Decreased mind-body coordination
So how much water should we drink in order to avoid these symptoms? Well experts state that loosely 8-10 glasses of water a day should be enough, however in hot and humid environments and after periods of exertion more water may be required. Another more accurate measure is keeping in mind the lifestyle, one litre for every 30 kgs may be good enough.
The human body has a built in mechanism of thirst that can notify us when we’re low on water. This mechanism is however far from perfect. by the time we feel thirsty. We’re already considerably low on water levels in the body. The best indicator of adequate hydration is clear or pale urine and no thirst. Keeping a water bottle and taking frequent sips can easily help us achieve the optimal water levels.
